The Bomag 31781871 Filler Cap is a genuine OEM component designed for BC 771 RB and BC 771 RS refuse/landfill compactors. Sourced directly from Bomag, this filler cap delivers an exact match to the original specification, ensuring a secure, leak-free seal on the fluid reservoir it serves. It is a direct replacement for the factory-installed cap on these machines, so installation is straightforward with no guesswork on fitment.
Key Features
- Genuine OEM Seal Integrity — manufactured to Bomag's original sealing specification, ensuring the cap seats correctly and maintains a contamination-free fluid system
- Direct-Fit Replacement — threaded and dimensioned to match the original filler neck on the BC 771 RB and BC 771 RS, dropping in exactly as the factory cap did
- Confirmed Compatibility — verified fitment for BC 771 RB and BC 771 RS refuse/landfill compactors
- Contamination Protection — a correctly sealing filler cap keeps moisture, dirt, and debris out of the fluid system, protecting internal components from accelerated wear
- Authentic Bomag Part — carries the genuine Bomag part number 31781871, so you can be confident you are ordering the correct cap the first time
A filler cap seals the opening of a fluid reservoir — such as a hydraulic tank or fuel tank — preventing contaminants like dirt, water, and debris from entering the system. On heavy refuse and landfill compactors like the BC 771 RB and BC 771 RS, which operate in demanding, debris-heavy environments, maintaining a proper seal is critical to protecting fluid quality and the components that depend on it. A damaged, missing, or ill-fitting cap can allow contamination to enter the system, leading to fluid degradation and premature component wear that can sideline the machine.
